In fact you could get the same error in your sample just by modifying your c# code with the corresponding VB code. It seems like C# has no issue. I wonder why. Hope you get the same error as mine.

Thanks.

Regarding the image button fullpostback issue, I have forward this to our development team and they will check it first. If the issue confirmed as a bug then we will fix it.

About the error that you have in your page, I need to check your page first or could you modify my sample page so it can replicate your issue and send it back to me?

One more thing. In the sample, asynchronous post works only for the asp button, while both imagebuttons are doing postabacks?

I think you didnt get what am saying . I said, the sample works fine for me, eventhough its html table. How? It throws no compile time or runtime error why?

Hi
The following line
wfpmBlocks.ClientAction.RenderControl(Master1)
throws error in my webpage. The reason simply was that Master1 is html table not asp table. However i cant understand that, its not giving any error in your sample. The only difference is that the solution provided by you is in C#Language and am working on VB language. On a normal case, the above line should throw error in both webpages, but its not. So an explanation is needed here

Try to put Master1 into an ASP.NET panel (asp:panel) for e.g: panel1 and then you can try to render the panel instead of the Master1.

wfpmBlocks.ClientAction.RenderControl(panel1)

Hope this helps.

Thanks for the sample. Its working fine for me. So am confused what would went wrong for me in my webpage. I will check that soon and will give you a reply. Or will reproduce the error on a simple sample if possible. however theres a performance penality as i can see from your sample. As you are colouring the first td, you are rendering it. dtc. But in my case the i dont know which td am gonna update. May all 56 tds ...that means inside a loop i have to call rendercontrol. Anyway let me check this on my page....

About webflypostback: I have tried using the samples and tutorials and played around doing some modifications. However when i applied webflypostbackmanager in my project, it is not working as it should be. The following is the design code of wfpm, if it would help.

 <ISWebDesktop:WebFlyPostBackManager ID="wfpmBlocks" runat="server" EnableUIMode="true" UpdateMode="AllControls">
 <FlyPostBackSettings PostControlState="True" PostHiddenFields="True" PostInputControls="True"
      PostViewState="True">
</FlyPostBackSettings>

However except one control all controls are causing fullpostback. And moreover only a partialupdate is caused. I will explain. My scenario is as follows. I have got an outer asp.net panel, and inside that an html table is located. For this table i have got two rows.On the first row i ve got a datepicker. On the second row, i have got another table with 9 rows and 8 td each. The design as follows. Full design is out of scope, hence am omitting 7 repeating rows.

<table cellpadding="0" cellspacing="0" border="0" style="height: 100%; width: 100%;">
                        <tr>
                            <td style="height: 1px;" colspan="2">
                                <table id="Tab1" runat="server" class="patient" width="100%">
                                    <tr>
                                        <td class="calendar" style="white-space: nowrap; vertical-align: middle;"> The datepicker comes here
                                        </td>
                                    </tr>
                                </table>
                            </td>
                        </tr>
                        <tr>
                            <td style="width: 99%; height: 100%;">

The above is the small part of my design, which is relevant to the question.When datepicker is clicked all labels are updated without any problem, asynchronously(for eg:those with id starting with dtc). Am adding some labels dynamically to the panels with class=schedueldataholder. When asynchronous post is made these labels are never get updated or removed. However i can do it work by making clientaction.markasdirty(panelID). This is done just after updating the panels in my code. But tell me if there is any performance penalty in doing this, as each panel is put as dirty once it is iterated. Now am applying background color to td. however i cant remove the color or change it because markasdirty option is not applicable to td or to table container. So i changed the markasdirty option to be applicable to entire panel holding all these controls. Am getting error like an alert box showing error message. Now for img1 and img2 full postback is only working. Why? Am not using custom update mode. However i tried with custom update mode and added these two controls and datepicker to the list. Now all controls are causing full postback. I even used updateviewstate for the first problem. The following is the server code.

listener = New WebFlyPostBackListener(Me)
wfpmBlocks.ServiceUrl = "ScheduleCalendar.aspx" & Request.Url.Query

Hope someone can help on this.
